Leiomyosarcoma of artery and vein

Five cases of leiomyosarcoma of blood vessels--three venous, two arterial--are reported. Treatment was surgical alone in two patients with involvement of the internal mammary artery and the long saphenous vein. The other three were treated initially by surgery, followed by radiation therapy, and surgery aimed at either total or partial removal of metastases. Two patients are alive and well, free of disease. Two patients have died of their disease despite all modalities of treatment, and one patient has a life-threatening metastases and is not expected to survive.
